SASH-PULLEY.

Specification of Letters Patent.

Patented Jan. 18, 1921.

Application filed August 21, 1920. Serial No. 405,034.

Y '0 all whom it may concern:

Be it known that 1, CHARLES FOUNTAIN YOUNG, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented new and useful Improvements in Sash-Pulleys, of which the following is a specification.

My invention relates to window sash pulleys of the type that require no screws to se cure them to the window frame.

My improved device is so constructed that when the pulley and its casing is placed in the mortise and the face plate pressed into position, the face plate and easing interlock so that the face plate will not accidentally become dislodged; and the casing will be firmly seated against the frame.

My invention is illustrated in the accom' panying drawings, in which Figure 1, is a side elevation of my im proved pulley in position in the frame, with parts of the frame cut and broken away exposing the complete device to view.

Fig. 2, is a rear elevation of the pulley in position in the frame.

Fig. 3, is a cross section on the line 3-3 of Fig. 2, and

Fig. 4, is a perspective of the face plate and its attached spreader-s.

Referring now to the drawings, F is the window frame, in a mortise in which, is seated a pulley casing made of two similar parts 0, C preferably made of sheet metal with a projection 0 on one part fitting into a recess 0 in the other at each end, and flanges c on the outer edges which are adapted to seat firmly against the frame to prevent the device slipping through or too far into the mortise for safety, and proper operation. The pulley 0 is pivoted between the members of the casing.

On either side of the pulley there is formed in the casing, tongues a, with an outwardly extending portion 0 on the free end, adapted to be bedded in or to extend back of the frame. These tongues are integral with the sides C. C and there is a head 0 on each, preferably where the portion 0 turns outwardly. On the inside of the tongues are guides c". The purposes of 0 and a will be hereafter pointed out.

A face plate D, is preferably cut from sheet metal, with a space d, left for the pulley, and two Spreaders at substantially at right angles to the body of the plate. These Spreaders are made wedge shape at the free end so as to press against the tongues 0 as the plate is forced into position and with notches 0Z to receive the beads 0 The spreaders (Z and the guides 0 cause the spreaders to bear upon the inner surface of the tongues a, forcing them outward into engaging position with the window frame, and guide the face plate D into correct seating position as it is pressed into place for use.

I claim as my invention and desire to secure by Letters Patent of the United States 1. A sash pulley device embodying a casing having tongues thereon, Spreaders on its face plate to press the tongues outwardly into en agement with the window frame, and saicl casing and face plate.

2. A sash pulley having in combination a two-part casing, a pulley wheel pivoted between the two sides of said casing, means on the casing for holding the casing securely in position in the window frame, and a face plate with spreaders adapted to con tact with said means and force said means outward into engagement with the window frame.

3. A sash pulley having in combination a two-part casing, a pulley wheel pivoted between the two sides of said casing, laterally expansible means on the casing for holding the casing securely in position in the window frame, and a face plate with spreaders adapted to force outwardly the laterally expansible means when the face plate is pressed into position for use of the pulley.

4. A sash pulley having in combination with a casing, a pulley wheel pivoted therein, tongues on the casing, a face plate, Spreaders on the face plate adapted to press against the tongues and force them outwardly into engagement with the window frame, and guides on the casing to insure the proper positioning of the face plate as it is pressed into place for use of the pulley.

5. A sash pulley device consisting of the pulley wheel and casing and a face plate; with tongues on the casing, spreaders on the face plate to press said tongues outwardly into engagement with the window frame, and means onboth the tongues and the Spreaders for holding the face plate in position When it has been pressed into place for the pulley to be used.

6. A sash pulley device having in combination a casing; a pulley wheel pivoted in said casing, tongues on the casing, a face plate, spreaders on the face plate adapted to press against the tongues and force them outwardly into engagement with the Window frame, guides on the casing to insure the proper positioning of the face plate as it is being pressed into place for use of the pulley, and means for interlocking the tongues and sprcaders when the devne has been put in position for use in the window 15 CHARLES FOUNTAIN YOUNG.
